.H'Thi'sinvention relates to vcushion apparatus for vehicle Wheels.:

very desirable Ato rvprovide aA substi; tute or'pneumatic tubes for sustaining rubber tires -andsuch is the'general: purpose kof the'l present" invention;

" A further ob3ect 1s toj-providewior -the l desired resiliency and Wholly eliminate the troubles incident to the` use ofair tubes. Another object is to avoidthe use ofyany formi ot'metallic {sp1-ing. Another is tozpro.-

vide a primary cushion medium and a firmer secondary cushion means.

A Y vent-ionaltype.v The usualiniatable tube off f @.Additional ob'ects are. :to provide ajcusln` ion means bodily insertible into `the standard' ouconvent-ional tire carcass. Without change thereotfand inthis connection to: provide cushion apparatus readily combinable with standardtires and Wheel structures Withgbut small cost of yadaptation and without materially mutilating the same. A still. further' purpose is to provide for the ready variation of the degree ofresiliency of the cushion 'mea-ns Without the removal of; any part of the apparatus or of the Wheel equipment.

Other objects and advantages vvillV be made apparent in the ensuing specification of anv embodiment of thev` invention illustrated herewith; it being reserved that `moditications, variations and vvadaptations may be resorted to within the principle, scope and Aspiritof the'invention as it is yhere claimed.

Figure 3 is a plan of aportion ofthe pri. i e, mary cushion pad. e l Y Figure 4c isa perspective of a rim clip. Figure 5 is a plan of a 'pad hacker jack.

Figure 6 isV a plan of a setof 'clincher plates. y The invention is shown as adapted to a I Wheel including a elly F having a clincher lrim R receiving a tire carcass T of consuch tires is Wholly' eliminated and' in its place a continuous, circular pad Vis intro-IA duced.

The pad 2 includes a heavy fabric base 2a, semicircular in cross-section, on Which is Well vulcanized a-crescent-sectlon'of rubber y in peripheral beads 3-39; the former or 1nafmdt beademing da and al@ haar beadsy being much firmer.- :At suitable inter- `metalsegments 5, of .arc-section,- inatchin'g 6 for-'iballjoints l7:.of removable jackstems Wheel fente-f@ passedthrough.hoieafein the hollovv ofthe circular pad 2.,;Each backl i Y ling segment 5l has'one 'ormorejball sockets l '8 which, a't'terfthe assemblyLof, the tire .on the- .V i'

@After the pad 2 andthe-backers 'fha've .been vlaidin thedismounted c,arcassI;Ineans f' are introduced to staythesidevvalls'ofthe pad 2 and also tolock or clinch them along the contiguousinside of the flanges of the rim R; when this type of rim is used on the l Wheel. v i Thelocking means includes pairs site lock plates 10 having shoulders 11 of opipo;

thrusting against'the near edges of the Walls abut Wedges 13 .through which y the -jack stems 8 extend radially ofthe Wheel.

`7hen the lock means hasbeen placed thefcarcass this is'slipped onto thevrim.-

Atsuitableinterv'als along the felly are,Vv

secured clips 15 havingthread'ed` holes 16 registering with the holes 9. v

In order to set the Wedge parts aseries of hollow screwsl? are'provided, each screvv having a largey lhead 18' threaded externallyV at 19. f The screws are' run into holes 9-16 yand engagethe-inner ends of Wedges 13 and as these .are` pressed outvvard'they engage the faces 12 of the side plates 10, which are so located as to force the carcass'lvvalls out against the rim iianges. The head 19` has wrench faces 20 for a suitable tool.

The secondary cushion includes 'a series of barrels21screvved on the heads 18. `Each barreljhas eXteriorQthreads 22 receivingV a jam nut 23 setting against a cup 24: which encloses a block of firm rubber 25. This rubber block constitutes a variable cushion sup- ,j porting the near end of the relative jack Y ably support the jack stems 8.
